I'd trash that thing or relinquish it... It's too much of a weight for me if I do any of those things... I think I'd rather finish my life peacefully, than have a conscience that I killed someone.
I think I would never use it. Most likely I would burn it or destroy it somehow.
First I would probably do like Light did. Laugh at it and think it was a joke, but then I would probably take it and destroy it. There is not a chance that I would even think of trying it. I'm against violence in most cases, so killing is a no-go.
I would use it for justice and kill criminals. Light did the right thing with it. If the deathnote should be used then it should be used for justice. Criminals need to be punished and putting them in jail does not always work. Some criminals get out of jail and they can hurt many people. But if criminals just started to die and the criminals didn't know how or why it is happening then some criminals will stop doing crimes.
